This repository serves as a template to base future CAN codebases upon.
canlib/ is a git submodule pointing to canlib, the team's common CAN library.
nbproject/ is where MPLAB X (the IDE we use for PIC microcontrollers) stores its configuration.
Makefile is also maintained by MPLAB X, which uses make internally.
device_config.c/.h sets the configuration bits for the microcontroller and has the code to initialize the external oscillator. We mostly leave this alone.
main.c is the entrypoint and contains both initialization code and the main loop, along with interrupt handlers. In this template it simply sets up CAN, blinks an LED, and responds to the MSG_LEDS_ON and MSG_LEDS_OFF CAN commands.
platform.c/.h defines the hardware-specific functionality like GPIO pinouts and peripheral initialization code. In this template it just sets up control for 3 LEDs.
